PHOENIX (AP) — An advisory for ozone levels possibly exceeding the health standard is in effect for the Phoenix area on Wednesday.
The Arizona Department of Environmental Quality says a predicted directional shift in the winds may trap ozone in high concentrations in the central and western part of the metro area.
The department urged children and adults with respiratory ailments to avoid outdoor activities. The general public also should limit activities outdoors throughout the day.
The Maricopa County Air Quality Department also will enforce its mandatory “no burn” restrictions throughout Wednesday.
Meanwhile, an excessive heat warning issued earlier for this week for the Phoenix area and nearby desert communities in south-central Arizona is set to expire Wednesday evening.
The weather service says isolated showers and thunderstorms are possible through the end of the week, with an increasing change early next week as moisture increases.
